Polyester-cotton blended fabric flame retardant
In this paper, the flame retardant properties and finishing conditions of polyester blended fabric flame retardant are studied. The comparison shows that the flame retardant effect of the flame retardant is improved by pn-1 and pn- 2. The damage length and fabric growth of the fabric after n-1 was less than pn- 2, and the fracture strength of the fabric after pn-2 was better than pn- 1.
Polyester/cotton blended fabric with excellent performance and sturdy, welcomed by consumers, however, because they are easy to burn cause fire accident, and lead to enormous losses, and therefore the study of flame retardant finishing is commonly concerned. So far, it has been found that the flame retardancy of the polyester fabric is far more difficult than that of any of the components.
The reason mainly has: first, because cotton is a flammability fiber, not melt not contract when burning terylene products, cotton fiber carbonization, a species seems to be on polyester candlewick support role, which impedes the development of polyester molten drops out of the fire; Second, polyester and cotton two polymers or their mutual induction heat cracking product, accelerated the overflow of pyrolysis products, thus terylene fabric fire speed is much faster than pure polyester and cotton. Third, during combustion, flame retardants can be transferred between polyester and cotton. Therefore, it is also difficult for the flame retardant of polyester fabrics.
At the same time, polyester-cotton blended fabric is heated, the heat melt polyester components will be covered in the surface of polyester fiber, and polyester fiber and its carbon skeleton to form generated by the pyrolysis, stop the fabric shrinkage, the molten polyester as a fuel fire area, make the fabric more severe burning.
Therefore, to reduce the flammability of polyester-cotton blends, the following points: (1) the flame retardation of each component in the blended fabric. (2) when the blended fabric is flame retardant finishing, the appropriate flame retardants are used, and the best of them can be complementary or non-interference. (3) eliminate the effect of bone price and the interference of two groups.
Isopropylphenyl Phosphate(IPPP35) Use
The Product Is Used For Rubber Products And PVC Plastic Flame Retardant Conveyor Belt, Cable, Chloroprene Rubber, Rubber And Other Synthetic Rubber Flame Retardant Plasticizer, Isopropylphenyl Phosphate Flame Retardant IPPP35 Use Also Applies To Fabric Coating, Circuit Boards, Flooring, Textiles, PVC, Phenolic Resin, And Other Fields.
Isopropylphenyl Phosphate Flame Retardant IPPP35 Halogen-Free Phosphate Flame Retardant Plasticizer, Which Does Not Pollute The Environment Twice. It Is The Lowest In The Phosphate Species And Has The Highest Phosphorus Content. This Product Is Colorless And Transparent, Good Compatibility, The Use Of Both Flame Retardant And Plasticizer, In The Flame Retardant And Plasticizer To Play A Balance Between The Role, But Also To Make The Processing Of The Same Material And Its Physical Properties.
Department of phosphorus and nitrogen flame retardant is one of the most effective flame retardant polyester/cotton blended fabric, at the same time, due to the synergistic effect between phosphorus and nitrogen, in the application of polyester-cotton blended fabric has a great development. In this paper, we use tetrahydroxymethyl chloride (THPC) to react with amide compounds and ammonia to form a water-soluble precondensate as the flame retardant pn-1 and pn- 2.
The flame retardant pn-1 and pn-2 were used to have a clear coeffect of phosphorus-nitrogen flame retardant system on the solid flame retardant of cellulose fiber. Because the addition of nitrogenous compounds can reduce the dosage of phosphor flame retardants, the flame retardant effect is improved. At the same time, nitrogen and phosphorus first formed the phosphamide structure, and then the p-n bond was generated, which enhanced the reaction capacity of phosphoylation with fibrous hydroxyl, and inhibited the formation of left-handed glucose.
When the fabric is ignited, the phosphorus in the flame retardant polymer reacts with the oxygen in the air to produce phosphorus oxide (p). 2 o? 5), phosphorus pentoxide is a kind of strong dehydrating agent, can take out of the water molecules from the fiber, phosphorus pentoxide met after water, generated the polyphosphoric acid, poly phosphoric acid will continue to remove the water from the fiber, is actually the cellulose reduction be non-combustible carbon, at the same time polyphosphoric acid was easy to coating on the outside of the fiber, thus inhibiting reaction with oxygen, avoid to generate combustible gases carbon monoxide.
When the cotton fiber carbonization, equivalent to carbon fibers, it became a skeleton of a synthetic fiber, synthetic fiber distribution in the middle of the carbon fiber, synthetic fiber most at this time also can't burn with fiber carbonization, the result is to prevent the burning of fabric.
In this paper, the flame retardant properties and finishing conditions of the flame retardant pn-1 and pn - 2 are studied.
Test reagent: pn-1 and p-2 (self - control) of polyester-cotton blended fabric flame retardant. Organosilicon softener sr, JFC osmotic agent, etc., are industrial grade. Formaldehyde, urea, melamine, triethanolamine, naoh, h2o2, na2sio3, naac, na2co3, etc., all of the reagents are in the market of ar and cp.
